Dr. Ciaran Byrne:

If I may make a point, as a general rule of thumb, it is always easier, quicker and cheaper to do it the first time. As when we discussed the retrofitting piece, to go back and do something afterwards is going to cost more. As the Deputy has correctly pointed out, if we can plan this in, where we have discussed district heating areas, where we know we need homes and can layer those up, it is probably ultimately cheaper to do it right the first time than to have to go back in afterwards.
